Taking a Look at Malaria

Satisfactory Essays
Malaria is an extremely deadly parasitic disease transmitted by the bite of a mosquito called plasmodium. This pathogen was discovered a long time ago and since then, a profound study has been made. From the studies made, scientists discovered that plasmodium vivax, plasmodium malariae, plasmodium ovale and falciparum are the four types responsible of human malaria. However, plasmodium vivax and falciparum are the most common (CDC).
Malaria has been an issue in many African countries, such as Angola, while in United States it was completely eradicated. Currently, about 40% of the world and especially in the poorest or third world countries, malaria has been the main killer (WHO). Additionally, according to world health organization (WHO), approximately 660,000 people died from malaria in 2010 globally and most of them were African children. Furthermore, yet in the same year, an estimated 219 million cases of malaria infection worldwide were registered.
Among the four types of parasites of malaria, plasmodium falciparum is the deadliest type. Malaria is usually transmitted from person to person by the bite of a female mosquito genus of the protozoan parasite Anopheles that needs blood for its eggs. Those microscopic parasites are transported via bloodstream to liver. Once they reach the liver, they start to damage the liver’s cell and their reproduction begins. The liver after the attack becomes swollen, causing its cell to burst and consequently, it releases the merozoite which is an egg cell, beginning then their life cycle. In addition, once the merozoite finds the perfect conditions in the bloodstream, it rapidly invades the red blood cells and begins to grow and at this point, symptoms of malaria start to become visible. It is difficult to detect the earlier symptoms of malaria because depending on the patient, it might not be specific. However, after ten to fifteen day after the mosquito bite, a patient may experience symptoms such as headache, muscle pains, abdominal discomfort, fatigue, vomit, fever, etc.
Furthermore, the malaria parasites also destroy the intracellular proteins present in the red blood cells, mainly the hemoglobin, infecting the red blood cells and causing its rupture. Additionally, the more the red cells are destroyed, the less the hemoglobin will be available, causing anemia. And if actions of treatment don’t be taken, serious complications may rise such as restriction of blood flow to the brain, damage of other vital organs, malaria cerebral and even death.
Malaria is a very danger pathogen and its necessary to don’t be neglected once diagnosed.
